wd: CSS add the letter space
value to the existing/default character spacing provided by the
UA

jr: our issue has to do with the
prescriptive nature of the SC. if a UA chooses different values
to they fail.

wd: UA should do the whole
range.
... character spacing is most effective at .1

jr: we need a range - min to max
and a step range

wd: that would be the way to do
it.
... not necessary to be so prescriptive

line 1.2 to 2

character .01 to .1, much beyond it slows the
reader down.

ja: word spacing. Only in
CSS.

gl: are there spacing
requirements that could be made AAA because it is CSS specific
and we are trying to make technology agnostic

wd: word spacing could be moved
to AAA
... CSS will change word spacing automatically when changing
letter spacing. No good research on word spacing.

gl: word spacing in CSS is
independent of letter spacing, letter remains intact with extra
space between words.
... could move word spacing to 1.4.6 and removed from 1.4.3

<Jan> WD: Really useful Line
spacing 1.2 TO 1.5

<Jan> WD: But top of the
range should be 2.0

<Jan> WD: Character spacing
MIN 0.02 to MAX 0.1

<Jan> WD: Word spacing can
move to 1.4.6 AAA

gl: increased % or em

wd: should be EM
... browser implementation is varied
... should use EM units, common in typography

<Jan> WD: Character spacing
concept is the amount to be added to the base character
width

<Jan> GL: character
spacing..."Increased by amount..."

gl: 'letter spacing increased by
X'

wd: some browser remove
proportional spacing when user starts adjusting letter spacing.
but varied implementation not very important, because user
still benefits.
... font would still be ARIAL but more space between character,
seems almost fixed width.

gl: could keep word spacing at AA
for technologies that support it and AAA for others
... units, "time base character width (em)" suggested
wording
... would eliminate typography jargon.

wd: many of the times in AAA need
margins and padding to be less to make reading easier.
... battle between large print and space on the screen. adjust
font size, then color, then spacing, repeat cycle. fit the most
information in the smallest space that user can still see
... there is one need group that would need column width and
spacing issues to be AA
... folks with 'tunnel vision' need the reduced spacing
... other group - vision loss (glaucoma) can only see in the
middle
... need narrow columns, closer line spacing, etc

eh: want more info about word
wrapping and narrow columns.

kp: this is true for mobile also.
horizontal scrolling pops up and is difficult for users

wd: will have research on
horizontal scrolling and reading speed etc. by mid summer

eh: does column width rate a
higher value in the guidelines

<Jan> 1.8.9 Allow Viewport
Resize: The user can resize viewports within restrictions
imposed by the platform, overriding any values specified by the
author. (Level AA)

wd: should be a higher
value
... borders and text style of 1.4.5 should be AAA, margins
should be AA

ja: problem in CSS there is no
column width (except tables), in ms word you have a feature to
make 1-6 columns with word wrap and flow. not in css

eh: need to capture this issue.
is there a solution, do we need to track this.

wd: good responsive design
(author controlled) should cover this.

<Jan_> 1.8.16 Linearize
Content: The user can have recognized content rendered as a
single column, overriding author-specified formatting of
columns, tables, and positioning. (Level AA)

<Jan_> 1.8.14 Multi-Column
Text Reflow: The user can specify that recognized multi-column
text blocks each be reflowed into a single column. (Level
AA)

jr: 1.8.9, 1.8.15, 1.8.14 and
1.8.16 are also relevant.

wd: these should go a long way to
addressing the multi-column difficulties we discussed

eh: would this be something for
the implementing document to discuss this scenario.

jr: yes

wd: it is not an orphan
disability. fairly common in people.

jr: user should have ability to
manipulate the page to see what works

wd: low vision (with field loss).
visual impairment 1/1000 for ages 0-40, 2/1000 40-60, 4/1000
for 65+
... 2 categories - visual acuity loss and field loss (not pure,
lots of overlap), each group has different issues. some need
large print/other small print,
... cloudy vision, light sensitivity (albinism, others),
scattered field (hold head in odd positions to get vision in
best spot)
... Legge (psychophysics of reading) many good articles.
doesn't matter what caused the condition functional ability is
pretty much the same
